Review on TECHNIKS SUPER PRECISION COLLET ACCURACY by Doug Virden

Haven't run this yet and tested it with the indicator, I'm a fairly new machinist. My boss recommended this brand and said they always showed less than 0.001 inch runout. Compared to the cheaper ER collets I've purchased, the quality, fit, and functionality is a far cry from simply mounting it on my little Chinese CNC machine with a 1/4" end mill and prying it out just looks and feels way better than the cheap brands I've used. It will probably work for a bit of work on my manual milling machine too. I just felt the need to notice the big difference from cheaper brands and I want this review request removed from my inbox. $15, the normal price of course.
